Abstract: A blank of a machine component comprising teeth, and a method of producing a corresponding machine component. The blank has a surface provided to constitute outside-face end regions of the teeth, and has indentations, which are preferably realized by a forming operation, boundaries of the indentations constituting edge regions of the surface. In the alteration of the blank for the purpose of realizing the machine component, the teeth can be realized in such a way that remaining regions of the indentations constitute chamfers of tooth flanks of the teeth. Burr strands, which would have to be removed in a further operation, can thereby be prevented.

Abstract: Composite gear blanks are manufactured by placing a rigid centerpiece in a mold, optionally inertizing the mold, filling the mold by adding a liquid reactive mixture around the centerpiece, applying static pressure to the mold and polymerizing the reactive mixture so as to form a plastic outer part surrounding the centerpiece. The composite gear blanks thus made have improved values of normal and shear adhesion strength both at room temperature and at elevated temperatures of up to 120° C. and are particularly suited for making worm gear parts of automotive electronic power steering systems.

Abstract: A process for manufacturing plastic moldings while increasing the coefficient of viscosity of the raw material used to manufacture same and to a molding manufactured according to the process. To increase the loadability and the service life of moldings manufactured by injection molding, which are subject to dynamic loads during their use, the granular material used is tempered before the shaping processing in the injection molding process for a period of 10 hours to 30 hours at a temperature between 90 C and 150 C. Without resorting to higher-priced materials, highly loadable moldings can be manufactured by this process, which can be advantageously used by the manufacturer without a greater effort. A corresponding molding, such as a worm gear, manufactured according to the process from a granular material with an original solution viscosity between 180 mL/g and 190 mL/g, has a solution viscosity between 180 mL/g and 200 mL/g.
